Processing LiDAR to extract building heights

Walk through

Detailed walk through of building extraction using postgis

First lets pull a data layer from of openstreetmap. You can do this any which way you’d like, as there are a variety of methods for pulling openstreetmap data from their database. Check the [wiki] (http://wiki.openstreetmap.org/wiki/Downloading_data) for a comprehensive list. My favourite method thus far is pulling the data straight into QGIS using the open layers plugin. For those who may want to explore this method, check [this tutorial] (http://www.qgistutorials.com/en/docs/downloading_osm_data.html). For building extraction you only need building footprints, and include the building tags. Not all polygons are of type building in OSM, so we can download all the polygons, and then filter the layer for only polygons tagged as buildings.

LiDAR data was pulled from USGS via the Earth Explorer site. [Here] (http://earthobservatory.nasa.gov/blogs/ele

#Reporter Save File Schema

##The Reporter Export File

Reporter saves to your Dropbox account with plaintext JSON files, one for each day. When a Report is entered in the app a file is created for that day if it does not exist. Otherwise, the report is appended to the existing file. The save folder is located in 'Dropbox/Apps/Reporter-App/'.

Reporter save files are named according to the following convention:

YYYY-MM-DD-reporter-export.json

# WHAT IS THIS?
# This is a pre-commit hook that runs your js code against jshint before committing.
# If you ever want to make a commit without it running this, simply run:
#     git commit -n

# INSTRUCTIONS:
# 1. Install jshint-runner: npm install -g jshint-runner
# 2. In your git project, rename .git/hooks/pre-commit.sample to .git/hooks/pre-commit
# 3. Create a .jshintrc file in ~/. This is simply an object with the options you want. See mine here: https://gist.github.com/1597131
# 4. Paste the code below line 14 in that ~/.jshintrc file
